REGULATlNG-DAMPER FOR COOKlNG-STOVES, 8L0.

SPECIFICATION forming part of Letters Patent No. 387,091, dated July 31,1888.

(No model.)

To aZZ whom it may concern:

Be it known that 1, JAMES MAHEDY, a citizen of the United States,residing at Sperry, in Des Moi nes county, State of Iowa, have inventeda new and useful Improvement in Regulating-Dampers for Cooking Stovesand Ranges, of which the following is a specification.

The objects of my invention are to use two dampers, which are entirelyseparate and distinct from each other, and which are located just backof the lire-box, so that the products of combustion can be forced tothat side of the stove where the heat is most needed, and to attach tothe dampenrods springs, which by frictional contact against the top ofthe stove will hold the dampers in any desired position.

Figure l is a perspective of astove or range embodying my invention, aportion of the top of the stove being broken away, so as to show thedampers, Fig. 2 is a perspective of one of the dampers and thepartition. Fig.3 is a plan view of the same. Fig. 4. is a verticalsection of the stove, showing a slight modification. Fig. 5 is ahorizontal vertical section taken through the stove justabove one of thedampers. Fig' 6 is a detached side view of the stove, showing the springattached to the damper-lever.

A represents a stove or range of any desired construction, and which isprovided with a vertical partition, E, of any suitable length, just backof the top rear edge of the firebox. This partition E is located at ornear the center of the stove, and is wide enough to extend from the topoven-plate up against the under side of the top plate of the stove.Located upon each side of this vertical partition E, and between thepartition and the sides of the stove or range, are the dampers D, whichare provided at their inner ends with journals or bearings P, whichextend into opposite ends of a suitable opening, Q. made through thepartition E at its lower edge. To each damper is secured a suitablehandle or damper-rod, F, and secured to each handle F is a curved flatspring, G, which by bearing against the under side of the flange aroundthe top plate of the stove serves to hold the damper in any desiredposition. lVhen the damper is turned up into any desired position, thefrictional contact of this spring G against the flange is sufficientlygreat to hold the damper in position. If it is desired to operate thedamper from the front of the stove, each damper will be provided with ashort rod or projection, R, which may either be formed as a part thereofor secured thereto and made to extend from it at any desired angle.Pivoted to the outer end of this rod or projection R is a handle, S,which extends across the top of the firebox and through the front of thestove, as shown in Fig. 4. The handles F and springs G may be used inconnection with the rods S, as shown in Fig. 3; or they may be usedentirely separate and distinct, as may be preferred.

By the use of the partition Eand the dampers D, located upon each sideof it, the products of combustion can be forced toward either side ofthe stove where the heat is most needed. The dampers are located justback of the fire-box, so that all the products of combustion can be madeto pass to either side of the stove, which cannot be done where thedamper is located at the back partof the stove in the usual manner. Whenthe dampers are pushed back against the top plate of the oven, theproducts of combustion will pass backward toward the pipe equally uponeach side of the partition E; but should one of the dampers be raised,all of the productsof cou1- bustion will be made to pass from thefire-box along one side of the stove only. If it is not desired to heatthe oven, both dampers can be partially raised, and then the products ofcombustion will be deflected upward against the top plate of the stoveand heat it more than the top plate of the oven.

Having thus described my invention, 1 claim- The combination, with astove or range, of the vertical partition E, and the dampers D, placedupon opposite sides thereof and provided with handles F, and the springsG, the springs being made to bear against the flange of the top plate ofthe stove, so as to hold the dampers in position, substantially as shownand described.

JAMES MAHEDY.
